This is the official release of WFM Stereo on SDR#. It has a stereo enhancement that provides better stereo separation and higher audio fidelity, I have tested this against WRPlus and SDR# is much better audio wise, and keeping a lock on Stereo. You can watch me clicking FM Stereo on and off, and on the top of the screen you can watch the (( stereo )) icon go on and off. – Source
